Other Objects are to simplify regulators of this type now in use, to provide `means for limiting the extent of opening between the valve und its sont, to provide im improved connection between the movable ressure device and the valve-lever, ond to re uce the number'of' parte to e minimum.

- Seid weights Fig". 8 is a central vertical sec- 'tion of e regulator, showing my invention 1n struction capable oil'l use for the pur Ose of this invention. I prefer, however, t at the seine may be modo in two parts 114 l2, which I respectively term the body" and the i covert A flexible diaphragm 13 such es is interposed between the body 11 and cove;` 12 and divides the casing into an sir-specie 14 and e finid or gas space 15. As 1s wei knowng'the air-space is provided with s vent 16, herein shown in the upper well of the cover. n .Y j

Arranged centrally in the cover is e Vthreaded opening 17 into which is threaded e bushing 1b, having pivoted thereon e. lever 19, uided in its movements in a slotted lug 2f), frorned on said bushing. Said lever is fitted with s. weivht 21, adjustable thereon of vr oh it is held in any adj usted osition.

Movabie Witlrthe flexible diep mgm is a. verti'elly-dis osed rod 23, that passescentreliy throng i seid diaphragm and is guided for movement in the bushing 1S.

Vvided with an inlet 28,-leving an e duit 29,openingfdownwardly into the Vees'- ing. The inner end of seid terbored, as et'SG, and e soft-*metal valve- 'seet 31 east iii-seid counterhore, said velve- -seet being concave to conform to the outline of e spherical valve to be presenti described.

Alever 32 is provided at one en with opposite pivot-trennioris, that enter pivot-holes in af pair of lugs 34, formed on ve plate 35, which is secured to the easing by a. nut 36, threaded onto a. screw-stud 37, formed on said plate and extending through en openin in the casing. To prevent' turning of `sin is commonly used in regulators of this kind,"A

The body ofthe regu]eter-oesii` is pro-VV ow-oon and rovided wit 1 e set-screw 22, by means is provided with a circumferential enge 24 and 'the flange 24 the diaphragm p 1311's? lever 179 ex rtste power thereageinst to conduit' is ooulk Y the lever therebetween, after which theyY are e closed upon the lever to cause the trunnions of the latter to enter the 'pivot-holes in the lugs 34. ln this manner a separate pivot-pin and the drilling of a hole through the lever is dispensed with.

The free end of the lever is located directly beneath the valve-scat 31 and provided with a seniispherieal pocket 38 and an opening 39, extending from said pocket through the lever. A s herieal valve ttl is loosely held in said poc ret an'd is revolved when nnseated by the pressure of the fluid as it issues from the inlet. In this manner the valve is freed from all adhering substances, and a perfect closure of the inlet is assured. The opening 39, leading from the pocket 3S, serves to discharge grit and other matter to the bottom ot the easing.

'The valve-lever 32 passes through a slot 41 in the diz'iphrngm-rod :23 and is provided with a V-shaped notch 42 in its under side, into which lits :in oplmsitely-inelined ridge 4l", whose inclination is greater than the inclined walls of said notch7 thus serving as a t'ulcrumpoint for the valve-lever and by reason ofthe di|l`erence in the inelination or angle ot the notch and the ridge all'o'rds the eleuranee neeessary to a tree action of the lever. ln this manner the drilling ot pivot-holes and the use of a pivotfpin are dispensed with, resulting in u construction which can be eusil')r assembled and as readil'utr disassembled.

The distanee between the inner end ol the inlet-ronduit und the l'ree end of the. valvelever when it itsl lowermost position should be less than the diameter ol the vnlve7 so that the valve cannot beeoine dislodged l`1om its retaining-pocket. For this` purpose l provide u set-screw 4?), which is passed through the bottom ol" the eusing and isndjustuble to limit the downward movement of the valvelever, n clamping-nut 44 being employed to retain the set-serew in :nrtv adjusted position.

ln Fig. S l have shown the ball-valve lll provided with a stem 4.3, that extends through the opening 39 in the valve-lever. Surrounding the protruding end of said stern between the valve-lever and a collar 46 on said stem is a spiral s ring 47. This construction permits the all to move freely within certain limits, while holding the same securely to-y 1. In a pressure-regulator, the combina-- tion with a casing having an outlet and an inlet provided with a valve-seat, a movable pressure device, a lever having opposite trunnions at one end and held in operative'connection with said pressure device,l a casting bearing against the bottom of the casing and having two apertured lugs for the reception of the trunnions on said lever and having also a screw-stud passing through the side wall of the casing, a nut screwed onto the protruding end of said stud, and a valve Carried by said lever' and serving to open and close said inlet.

2. In a pressure-regu]ator, the combination with a easing having an outlet and an inlet elbow-conduit provided with a cone-lived vulve-seat, a movable pressure device, a pivoted lever operativelyr connected with said pressure device and having :1 eoneaved pocket and an opening ,Xtending from .said pocket through said lever. und a spherical valve located in said poeke` substuntiall)Y :is and `for the purpose described.

3, ln a pressure-regulator, the combination with a casing having an inlet and an outlet, a movable pressurcdeviee within said cesing, a lever pivoted :it one end and having operative e( ilection with said pressure device, a valve at the free end of said leverT and a set.- serew extending through the bottom of the easing with its free end in the path of suid lever to limit the movement thereof.
